How to get alerted when server was rebooted

Modified on: Thu, 28 May, 2015 at 9:06 AM

Reboots can happen due to OS update, server crash, or due to user error. Since CloudMonix checks for outages once per minute, it may not detect an outage in a server if the server is recovered quickly enough. Sure way to get alerted on a server reboot is to inspect the value of System Uptime performance counter. It resets to 0 every time the server reboots.

Steps to get alerted when a server reboots are as follows (this works for any Windows-based server for which CloudMonix can track performance counters)

Capture system uptime metric by tracking a new WindowsPerformanceCounter with PerformanceCounter Category System and Counter System Up Time

Setup a new alert that checks when Uptime is less than 10 minutes/600seconds (or longer if a particular server takes a long time to startup)

When Uptime metric shows up on dashboards and starts "skewing" the look of data due to always increasing, it may be beneficial to hide it by un-selecting it from the dashboard
